HIV infection induces immune alterations, mainly in gut mucosa, where the main target cells reside. However, the evolution of the infection is variable among infected individuals, as evidenced by HIV controllers who exhibit low or undetectable viral load in the absence of treatment. The aim of this study was to evaluate the frequency, phenotype and activity of T and NK cells in peripheral blood...

The results of an ongoing FEM parametric study are presented regarding the dependence of the resulting piled raft behavior under lateral load and combination of loads on pile diameter, pile length, arrangement of piles and raft thickness. Taguchi method with Analysis of Variance (ANOVA) was employed to calculate the contribution ratio of these factors on the lateral displacement of piled raft. ...

drying, is one of the important postharvest processes of medicinal plants with an important role played in quality and quantity of the drugs. in this research, in order to study the effect of growing conditions and different drying methods on drying time, essential oil content, color characteristics and microbial load of dracocephalum moldavica, a factorial experiment in randomized complete blo...

Mahfouz Al-Bachir The objective of the present study is to evaluate effect gamma irradiation on microbial load, and physicochemical properties dried damask rosa petal (DDRP). Syrian DDRP was irradiated at 5, 10 15 kGy doses. Microbial sensorial samples its extract were investigated.

abstract cadmium is one of the heavy metals with a considerable importance for its potential toxic effects on soil microbial activities and composition. although, the toxic effect of cadmium on soil microbial activities is somewhat well-known, but the extent to which cd affects soil biota depends largely on soil properties and conditions, particularly soil organic matter contents. thus, the aim...

Current microbial methodologies to determine fish quality are laborious and have long time required to obtain results. The impediometric technique as a rapid sensitive method was used to determine the correlation between impedance detection times (IDTs) and conventional reference psychrophilic and mesophilic plate counts of fish in order to develop models for predicting the microbial quality an...

this study was conducted to investigate the bacterial contamination of small ruminant carcasses in traditional slaughterhouses of tehran province, in summer and winter seasons. 30 sheep and goat carcasses from slaughterhouses of rey, shahreyar and eslamshahr were evaluated. در انتهای خط کشتار و قبل از مرحله توزیع، از لاشه دامها نمونه برداری شد. randomly samples were taken at the end of the slau...

the number of vegetable processing plants has been increased during recent years in iran as many other countries. on the other hand, fresh vegetable products are susceptible to microbial contamination after harvest, processing, handling, packing and distribution. the aim of this study was to determine and evaluate the level of microbial load of vegetables during different cleaning steps in a fr...
